Do you think I have any reason to keep my 70-300 now that I have a 70-200 f4 is

Jul 9, 2008

I'm debating if it makes sense to sell my 70-300. I just got a 70-200 f4 is. I also own a Sigma 1.4tc. I don't like using the tc with the 70-300 because the back of the lens hits the tc if I zoom out too far. The lens is also very slow and soft with the TC. I can't see a reason to hold on to both of them. If I want more reach the 400mm f5.6L makes more sense. What do you think?
thanks
